[Anterior sternoclavicular dislocation, description of surgical technique].

Sternoclavicular joint dislocation is an uncommon injury and is usually consequential to high-energy trauma. These can be classified as anterior or retro-sternal (posterior) dislocation. Sometimes they can be accompanied by injury to large vessels due to their anatomical proximity mainly retrosternal. Conceptually closed reduction is indicated as the first line of treatment in acute injuries and open reduction tends to be for failing the previous one. We present a case of anterior clavicular sternal dislocation, with recurrence after closed reduction under anesthesia and surgically operated with reconstruction and allograft use with favorable evolution six years after its surgical procedure.
